Conscious sedation always used for angios?

Hello fellow rad nurses! Have a question I'd like the group to address - Do any of you have docs/radiologists that do angios without any conscious sedation??
I work with a variety of doctors - radiologists, cardiologists, and a vascular surgeon - all who do angios. The vascular guy allows us to give sedation to all of his patients; one of the radiologists never gives sedation, but he does keep the site numbed with Lido and his patients never complain. However - we just started doing cardiac caths and our cardiologist does not use sedation. First case he did was a right and left heart cath and I was very uncomfortable when he sized up to an 8 FR sheath. It was obvious the patient had a lot of discomfort. This particular cardiologist is new to our facility (in fact - he is new to our country) and I did ask one of the other cardiologists in the group to discuss giving conscious sedation with him. Seems to me we are not providing a consistent standard of care for all our patients. Any advise - suggestions on how to address this? By the way - I really enjoy this site and would love to see more postings and discussion!!
